Recommended SD Memory Cards For The Sony A6300
Best UHS-II Memory Cards
The Sony A6300 does not gain any speed benefits from using a UHS-II memory card. However, they do perform the same as USH-I cards in camera. If you’re looking for faster transfer speeds from your card to your computer and you also buy a USB 3.0 UHS-II memory card reader then UHS-II memory cards will drastically improve your performance when transferring to your computer.
Best UHS-I Memory Cards
For speed and performance compared to price, UHS-I memory cards are the way to go. Most people have success using Sony cards. But Sandisk and Lexar cards also work well as well. Stay away from Transcend and Samsung.

4k 100M Recording With Sony A6300
A lot of Sony shooters have a lot of trouble getting their memory cards to work properly when trying to shoot with the XAVC S codec with 4k 100M. I believe this is because Sony cameras will aggressively check each card after inserting into camera to determine if it’s U3 capable or not and often times these cards will fail and the camera will give you a message telling you to enter a U3 memory card. The only work around at this time is to buy a different memory card. Right now the Sony brand is performing the best. Lexar and Sandisk also work well.
4k 100M Requirements
It looks like SDHC memory cards as well as SDXC memory cards work for 4k video on the Sony A6300. Sony previously had issues with XAVS S working on SDHC memory cards but has been slowly rolling out new firmware that updates older cameras as well as releasing new cameras like the A6300 that come loaded with this feature.
You will however still need U3 memory cards to consistently record 4K 100M video.
Best SD Memory Card Sony A6300 Conclusions
I was a little bummed that Sony did not upgrade their camera to have faster memory card performances. They brag about how fast this camera can shoot and how good the auto focus is, but then you have to wait an eternity for the buffer to clear compared to the competition. Maybe next year we’ll start seeing some modern USB 3.0 performances out of Sony, for now, this is a pretty big disappointment.
However, for your casual shooter who doesn’t do a lot of burst shooting, you will likely not feel the effects of these slow performances and shooting will nothing but loads, no, buckets of fun! 🙂
